FIELD OF THE INVENTION

The present invention generally relates to the field of computer security and cryptography. In particular, the present invention is directed to methods and systems for distributed cryptographically secured data validation.

BACKGROUND

Physical asset transfers have become an increasingly complex process involving coordination among multiple parties dispersed among multiple locations. As a result, multiple discrepancies can arise, such as billing discrepancies between carriers as well as data inconsistencies among parties. As a result, this can lead to reduced productivity and increased time to complete a transaction.

The method includes generating, by the first validator, at least a second digitally signed textual element, the at least a second digitally signed textual element containing a reference to the at least a first digitally signed textual element and at least a first validity flag indicating a determination by the at least a second validator of the validity of the at least a first physical asset transfer field. The method includes transmitting, by the first validator, a second instance of the immutable sequential data structure to a plurality of second validators, wherein the second instance of the immutable sequential data structure contains the at least a second digitally signed textual element. The method includes receiving, by the first validator and from at least a second validator of the plurality of second validators, an indication of a conflict with the first validity flag. The method includes generating, by the first validator and as a function of the indication of the conflict, a third digitally signed textual element referencing the first digitally signed textual element.

DETAILED DESCRIPTION

At a high level, aspects of the present disclosure are directed to systems and methods for secure cryptographically secured data validation. In an embodiment, a physical asset transfer may be attested at various stages throughout the physical asset transfer to ensure accuracy and validity of information provided and generated. Attestations may be performed by various devices and/or users of devices. Attestations may reference different physical asset transfer data fields relating to different features of an agreement or contract governing a physical asset transfer. Attestations may be authenticated by other various devices and/or users of devices once information contained within physical asset transfer data fields has been confirmed. Attestations may be denied by various other devices and/or users of devices prompting generation of error flags. Error flags may prompt reconciliation and/or inquiry by other subsequent devices and/or users of devices. In an embodiment, error flags may halt movement of the physical asset transfer until errors are resolved. Such systems and methods provide numerous advantages by ensuring validity and accuracy of s physical asset transfer in real-time as it occurs. Further, in some embodiments error flags may halt movement of physical asset transfers until disputes are resolved so that chances of physical asset transfers arriving at incorrect destinations or with improper packaging are minimized. Transactions are posted to an immutable sequential data structure which assists in ensuring integrity of the system by distributing records of transactions across multiple devices.

In an embodiment, methods and systems described herein may implement one or more aspects of a cryptographic system. In one embodiment, a cryptographic system is a system that converts data from a first form, known as “plaintext,” which is intelligible when viewed in its intended format, into a second form, known as “cyphertext,” which is not intelligible when viewed in the same way. Cyphertext may be unintelligible in any format unless first converted back to plaintext. In one embodiment, a process of converting plaintext into cyphertext is known as “encryption.” Encryption process may involve the use of a datum, known as an “encryption key,” to alter plaintext. Cryptographic system may also convert cyphertext back into plaintext, which is a process known as “decryption.” Decryption process may involve the use of a datum, known as a “decryption key,” to return the cyphertext to its original plaintext form. In embodiments of cryptographic systems that are “symmetric,” decryption key is essentially the same as encryption key: possession of either key makes it possible to deduce the other key quickly without further secret knowledge. Encryption and decryption keys in symmetric cryptographic systems may be kept secret and shared only with persons or entities that the user of the cryptographic system wishes to be able to decrypt the cyphertext. One example of a symmetric cryptographic system is the Advanced Encryption Standard (“AES”), which arranges plaintext into matrices and then modifies the matrices through repeated permutations and arithmetic operations with an encryption key.

In embodiments of cryptographic systems that are “asymmetric,” either encryption or decryption key cannot be readily deduced without additional secret knowledge, even given the possession of a corresponding decryption or encryption key, respectively; a common example is a “public key cryptographic system,” in which possession of the encryption key does not make it practically feasible to deduce the decryption key, so that the encryption key may safely be made available to the public. An example of a public key cryptographic system is RSA, in which an encryption key involves the use of numbers that are products of very large prime numbers, but a decryption key involves the use of those very large prime numbers, such that deducing the decryption key from the encryption key requires the practically infeasible task of computing the prime factors of a number which is the product of two very large prime numbers. Another example is elliptic curve cryptography, which relies on the fact that given two points P and Q on an elliptic curve over a finite field, and a definition for addition where A+B=R, the point where a line connecting point A and point B intersects the elliptic curve, where “0,” the identity, is a point at infinity in a projective plane containing the elliptic curve, finding a number k such that adding P to itself k times results in Q is computationally impractical, given correctly selected elliptic curve, finite field, and P and Q.

Some embodiments of the disclosed systems and methods involve creation and/or evaluation of digital signatures. A digital signature as used herein is an encrypted mathematical representation of a file or other set of data using the private key of a public key cryptographic system. Signature may be verified by decrypting the encrypted mathematical representation using the corresponding public key and comparing the decrypted representation to a purported match that was not encrypted; if the signature protocol is well-designed and implemented correctly, this means the ability to create the digital signature is equivalent to possession of the private decryption key. Likewise, if mathematical representation of file is well-designed and implemented correctly, any alteration of the file will result in a mismatch with the digital signature; the mathematical representation may be produced using an alteration-sensitive, reliably reproducible algorithm, such as a hashing algorithm as described in further detail below. A mathematical representation to which the signature may be compared may be included with signature, for verification purposes; in other embodiments, the algorithm used to produce the mathematical representation is publicly available, permitting the easy reproduction of the mathematical representation corresponding to any file.

In some embodiments, persons, devices, or transactions may be authenticated or assigned a confidence level using digital certificates. In one embodiment, a digital certificate is a file that conveys information and links the conveyed information to a “certificate authority” that is the issuer of a public key in a public key cryptographic system. Certificate authority in some embodiments contains data conveying the certificate authority's authorization for the recipient to perform a task. The authorization may be the authorization to access a given datum. The authorization may be the authorization to access a given process. In some embodiments, the certificate may identify the certificate authority. The digital certificate may include a digital signature.

In some embodiments, a third party such as a certificate authority (CA) is available to verify that the possessor of the private key is a particular entity; thus, if the certificate authority may be trusted, and the private key has not been stolen, the ability of an entity to produce a digital signature confirms the identity of the entity and links the file to the entity in a verifiable way. Digital signature may be incorporated in a digital certificate, which is a document authenticating the entity possessing the private key by authority of the issuing certificate authority and signed with a digital signature created with that private key and a mathematical representation of the remainder of the certificate. In other embodiments, digital signature is verified by comparing the digital signature to one known to have been created by the entity that purportedly signed the digital signature; for instance, if the public key that decrypts the known signature also decrypts the digital signature, the digital signature may be considered verified. Digital signature may also be used to verify that the file has not been altered since the formation of the digital signature. Although digital signatures have been introduced here as performed using public key cryptographic systems, digital signatures may alternatively or additionally be performed using any non-interactive zero-knowledge proof; for instance, a proof may be recorded in conjunction with a datum, and a verification may be performed by any party seeking to evaluate the proof.

In some embodiments, systems and methods described herein produce cryptographic hashes, also referred to by the equivalent shorthand term “hashes.” A cryptographic hash, as used herein, is a mathematical representation of a lot of data, such as files or blocks in a block chain as described in further detail below; the mathematical representation is produced by a lossy “one-way” algorithm known as a “hashing algorithm.” Hashing algorithm may be a repeatable process; that is, identical lots of data may produce identical hashes each time they are subjected to a particular hashing algorithm. Because hashing algorithm is lossy, it may be impossible to reconstruct a lot of data from a hash produced from the lot of data using the hashing algorithm. In the case of some hashing algorithms, reconstructing the full lot of data from the corresponding hash using a partial set of data from the full lot of data may be possible only by repeatedly guessing at the remaining data and repeating the hashing algorithm; it is thus computationally difficult if not infeasible for a single computer to produce the lot of data, as the statistical likelihood of correctly guessing the missing data may be extremely low. However, the statistical likelihood of a computer of a set of computers simultaneously attempting to guess the missing data within a useful timeframe may be higher, permitting mining protocols as described in further detail below.

In an embodiment, hashing algorithm may demonstrate an “avalanche effect,” whereby even extremely small changes to lot of data produce drastically different hashes. This may thwart attempts to avoid the computational work necessary to recreate a hash by simply inserting a fraudulent datum in data lot, enabling the use of hashing algorithms for “tamper-proofing” data such as data contained in an immutable sequential data structure as described in further detail below. This avalanche or “cascade” effect may be evinced by various hashing processes; persons skilled in the art, upon reading the entirety of this disclosure, will be aware of various suitable hashing algorithms for purposes described herein. Verification of a hash corresponding to a lot of data may be performed by running the lot of data through a hashing algorithm used to produce the hash. Such verification may be computationally expensive, albeit feasible, potentially adding up to significant processing delays where repeated hashing, or hashing of large quantities of data, is required, for instance as described in further detail below. Examples of hashing programs include, without limitation, Winternitz hashing algorithms, various generations of Secure Hash Algorithm (including “SHA-1,” “SHA-2,” and “SHA-3”), “Message Digest” family hashes such as “MD4,” “MD5,” “MD6,” and “RIPEMD,” Keccak, “BLAKE” hashes and progeny (e.g., “BLAKE2,” “BLAKE-256,” “BLAKE-512,” and the like), Message Authentication Code (“MAC”)-family hash functions such as PMAC, OMAC, VMAC, HMAC, and UMAC, Polyl405-AES, Elliptic Curve Only Hash (“ECOH”) and similar hash functions, Fast-Syndrome-based (FSB) hash functions, GOST hash functions, the Grøstl hash function, the HAS-160 hash function, the JH hash function, the RadioGatún hash function, the Skein hash function, the Streebog hash function, the SWIFFT hash function, the Tiger hash function, the Whirlpool hash function, or any hash function that satisfies, at the time of implementation, the requirements that a cryptographic hash be deterministic, infeasible to reverse-hash, infeasible to find collisions, and have the property that small changes to an original message to be hashed will change the resulting hash so extensively that the original hash and the new hash appear uncorrelated to each other. A degree of security of a hash function in practice may depend both on the hash function itself and on characteristics of the message and/or digest used in the hash function. For example, where a message is random, for a hash function that fulfills collision-resistance requirements, a brute-force or “birthday attack” may detect collision may be on the order of O(2^(n/2)) for n output bits; thus, it may take on the order of 2²⁵⁶ operations to locate a collision in a 512 bit output “Dictionary” attacks on hashes likely to have been generated from a non-random original text can have a lower computational complexity, because the space of entries they are guessing is far smaller than the space containing all random permutations of bits. However, the space of possible messages may be augmented by increasing the length or potential length of a possible message, or by implementing a protocol whereby one or more randomly selected strings or sets of data are added to the message, rendering a dictionary attack significantly less effective.

Referring now to FIG. 1, an exemplary embodiment of a system 100 for distributed cryptographically secured data validation is illustrated. System 100 includes a first validator 104. First validator 104 may include any computing device as described or alluded to below in reference to FIG. 10. First validator 104 may include a plurality of computing devices as described below in reference to FIG. 10; plurality of computing devices may share computation or data storage tasks in any suitable way including parallel computing, sequential performance of specialized tasks, redundant or distributed computation or storage, or the like.

First validator 104 may contain, in memory of first validator 104, an instance of an immutable sequential data structure 108. Instance of an immutable sequential data structure 108, as used herein, may be an entire copy of an immutable sequential data structure 108, one or more blocks or other portions of an immutable sequential data structure 108, and/or a link to a copy of an immutable sequential data structure 108. Instance of an immutable data structure 108 may include one or more digitally signed textual elements 112. Turning now to FIG. 2, an exemplary embodiment of an immutable sequential data structure 108 is illustrated. Immutable sequential data structure 108 may include any set of data used to record a series of digitally signed textual elements 112 in an inalterable format that permits authentication of such digitally signed textual elements 112. In some embodiments, immutable sequential data structure 108 records a series of digitally signed textual elements 112 in a way that preserves the order in which the digitally signed textual elements 112 took place. In one embodiment, a digitally signed textual element 112 is a collection of textual data; as a non-limiting example, textual data may include data stating that the owner of a certain transferable item represented in the digitally signed textual element 112 register is transferring that item to the owner of an address. A digitally signed textual element 112 may be signed by a digital signature created using the private key associated with the owner's public key, as described above. In a non-limiting example, digitally signed textual element 112 may describe a transfer of virtual currency, such as crypto-currency as described below. Virtual currency may be a digital currency. The item of value may be a transfer of trust, for instance represented by a statement vouching for the identity or trustworthiness of the first entity. Digitally signed textual element 112 may describe the transfer of a physical good; for instance, digitally signed textual element 112 may describe the sale of a product. In some embodiments, a transfer nominally of one item may be used to represent a transfer of another item; for instance, a transfer of virtual currency may be interpreted as representing a transfer of an access right; conversely, where the item nominally transferred is something other than virtual currency, the transfer itself may still be treated as a transfer of virtual currency, having value that depends on many potential factors including the value of the item nominally transferred and the monetary value attendant to having the output of the transfer moved into a particular user's control. The item of value may be associated with the digitally signed textual element 112 by means of an exterior protocol, such as the COLORED COINS created according to protocols developed by The Colored Coins Foundation, the MASTERCOIN protocol developed by the Mastercoin Foundation, or the ETHEREUM platform offered by the Stiftung Ethereum Foundation of Baar, Switzerland, the Thunder protocol developed by Thunder Consensus, or any other protocol.

In one embodiment, an address is a textual datum identifying the recipient of virtual currency in a digitally signed textual element 112. In some embodiments, the address is linked to a public key, the corresponding private key of which is owned by the recipient of the digitally signed textual element 112. For instance, the address may be the public key. The address may be a representation, such as a hash, of the public key. The address may be linked to the public key in the memory of a computing device, for instance via a “wallet shortener” protocol. Where the address is linked to a public key, the transferee in the digitally signed textual element 112 may record a subsequent digitally signed textual element 112 transferring some or all of the value transferred in the first digitally signed textual element 112 to a new address in the same manner.

Immutable sequential data structure 108 may preserve an order in which the digitally signed textual elements 112 took place by listing them in chronological order. The ledger may preserve the order in which digitally signed textual elements 112 took place by listing them in blocks 200 and placing the blocks 200 in chronological order. The immutable sequential data structure 108 may be a distributed, consensus-based ledger, such as those operated according to the protocols promulgated by Ripple Labs, Inc., of San Francisco, Calif., or the Stellar Development Foundation, of San Francisco, Calif., or of Thunder Consensus. In some embodiments, the ledger is a secured ledger; in one embodiment, a secured ledger is a ledger having safeguards against alteration by unauthorized parties. The ledger may be maintained by a proprietor, such as a system administrator on a server, that controls access to the ledger; for instance, the user account controls may allow contributors to the ledger to add digitally signed textual elements 112 to the ledger but may not allow any users to alter digitally signed textual element 112 that have been added to the ledger. In some embodiments, the ledger is cryptographically secured; in one embodiment, a ledger is cryptographically secured where each link in the chain contains encrypted information that makes it practically infeasible to alter the ledger without betraying that alteration has taken place, for instance by requiring that an administrator or other party sign new additions to the chain with a digital signature. In lieu of a centrally controlling authority, such as a national bank, to manage currency values, the number of units of a particular crypto-currency may be limited; the rate at which units of crypto-currency enter the market may be managed by a mutually agreed-upon process, such as creating new units of currency when mathematical puzzles are solved, the degree of difficulty of the puzzles being adjustable to control the rate at which new units enter the market. Mathematical puzzles may be the same as the algorithms used to make productions of sub-listings 208 in a block chain computationally challenging; the incentive for producing sub-listings 208 may include the grant of new crypto-currency to the miners. Quantities of crypto-currency may be exchanged using at least a digitally signed assertion 200 as described above.

In some embodiments, immutable sequential data structure 108, once formed, cannot be altered by any party, no matter what access rights that party possesses. For instance, immutable sequential data structure 108 may include a hash chain, in which data is added during a successive hashing process to ensure non-repudiation. Immutable sequential data structure 108 may include a block chain. In one embodiment, block chain is an immutable sequential data structure 108 that records one or more new digitally signed textual elements 112 in a data item known as a block 208. An example of a block chain is the BITCOIN block 208-chain used to record BITCOIN digitally signed textual elements 112. Blocks 200 may be created in a way that places the blocks 200 in chronological order and links each block 208 to a previous block 208 in the chronological order, so that any computing device may traverse the blocks 200 in reverse chronological order to verify any digitally signed textual elements 112 listed in the block chain. Each new block 208 may be required to contain a cryptographic hash describing the previous block 208. In some embodiments, the block chain contains a single first block 208, known as a “genesis block.”

Creation of a new block 208 may be computationally expensive; for instance, the creation of a new block 208 may be designed by a “proof of work” protocol accepted by all participants in forming the block chain to take a powerful set of computing devices a certain period of time to produce. Where one block 208 takes less time for a given set of computing devices to produce the block 208, the protocol may adjust the algorithm to produce the next block 208 so that it will require more steps; where one block 208 takes more time for a given set of computing devices to produce the block 208, protocol may adjust the algorithm to produce the next block 208 so that it will require fewer steps. As an example, the protocol may require a new block 208 to contain a cryptographic hash describing its contents; the cryptographic hash may be required to satisfy a mathematical condition, achieved by having the block 208 contain a number, called a nonce, whose value is determined after the fact by the discovery of the hash that satisfies the mathematical condition. Continuing the example, the protocol may be able to adjust the mathematical condition so that the discovery of the hash describing a block 208 and satisfying the mathematical condition requires more or less steps, depending on the outcome of the previous hashing attempt. The mathematical condition, as an example, might be that the hash contains a certain number of leading zeros and a hashing algorithm that requires more steps to find a hash containing a greater number of leading zeros, and fewer steps to find a hash containing a lesser number of leading zeros. In some embodiments, the production of a new block 208 according to the protocol is known as “mining.” The creation of a new block 208 may alternatively be designed by a “proof of stake” protocol as will be apparent to those skilled in the art upon reviewing the entirety of this disclosure.

In some embodiments, mining protocol also creates an incentive to mine new blocks 200. Incentive may be financial; for instance, successfully mining a new block 208 may result in the person or entity that mines the block 208 receiving a predetermined amount of currency. Currency may be fiat currency. Currency may be crypto-currency as defined below. In other embodiments, incentive may be redeemed for particular products or services; the incentive may be a gift certificate with a particular business, for instance. In some embodiments, incentive is sufficiently attractive to cause participants to compete for the incentive by trying to race each other to the creation of blocks 200. Each block 208 created in block chain may contain a record or digitally signed textual element 112 describing one or more addresses that receive an incentive, such as virtual currency, as the result of successfully mining the block 208.

Where two entities simultaneously create new blocks 200, immutable sequential data structure 108, such as without limitation block chain, may develop a fork; the protocol may determine which of the two alternate branches in the fork is the valid new portion of the block chain by evaluating, after a certain amount of time has passed, which branch is longer. “Length” may be measured according to the number of blocks 200 in the branch. Length may be measured according to the total computational cost of producing the branch. A fork resolution protocol may treat only digitally signed textual elements 112 contained the valid branch as valid digitally signed textual elements 112. When a branch is found invalid according to this protocol, digitally signed textual elements 112 registered in that branch may be recreated in a new block 208 in the valid branch; fork resolution protocol may reject “double spending” digitally signed textual elements 112 that transfer the same virtual currency that another digitally signed textual element 112 in the valid branch has already transferred. As a result, in some embodiments the creation of fraudulent digitally signed textual elements 112 requires the creation of a longer block chain branch by the entity attempting the fraudulent digitally signed textual element 112 than the branch being produced by the rest of the participants; as long as the entity creating the fraudulent digitally signed textual element 112 is likely the only one with the incentive to create the branch containing the fraudulent digitally signed textual element 112, the computational cost of the creation of that branch may be practically infeasible, guaranteeing the validity of all digitally signed textual elements 112 in the block chain.

Additional data linked to a digitally signed textual element 112 may be incorporated in blocks 200 in the block chain; for instance, data may be incorporated in one or more fields recognized by block chain protocols that permit a person or computer forming a digitally signed textual element 112 to insert additional data in the block chain. In some embodiments, additional data is incorporated in an unspendable digitally signed textual element 112 field. For instance, the data may be incorporated in an OP_RETURN within the BITCOIN block chain. In other embodiments, additional data is incorporated in one signature of a multi-signature digitally signed textual element 112. In an embodiment, a multi-signature digitally signed textual element 112 is a digitally signed textual element 112 to two or more addresses. In some embodiments, the two or more addresses are hashed together to form a single address, which is signed in the digital signature of the digitally signed textual element 112. In other embodiments, the two or more addresses are concatenated. In some embodiments, the two or more addresses may be combined by a more complicated process, such as the creation of a Merkle tree or the like. In some embodiments, one or more addresses incorporated in the multi-signature digitally signed textual element 112 are typical crypto-currency addresses, such as addresses linked to public keys as described above, while one or more additional addresses in the multi-signature digitally signed textual element 112 contain additional data related to the digitally signed textual element 112; for instance, the additional data may indicate the purpose of the digitally signed textual element 112, aside from an exchange of virtual currency, such as the item for which the virtual currency was exchanged. In some embodiments, additional information may include network statistics for a given node, e.g. the latencies to nearest neighbors in a network graph, the identities or identifying information of neighboring nodes in the network graph, the trust level and/or mechanisms of trust (e.g. certificates of physical encryption keys, certificates of software encryption keys, (in non-limiting example certificates of software encryption may indicate the firmware version, manufacturer, hardware version and the like), certificates from a trusted third party, certificates from a decentralized anonymous authentication procedure, and other information quantifying the trusted status of the node 304 in FIG. 4) of neighboring nodes in the network graph, IP addresses, GPS coordinates, and other information informing location of the node and/or neighboring nodes, geographically and/or within the network graph. In some embodiments, additional information may include history and/or statistics of neighboring nodes with which the node has interacted. In some embodiments, this additional information may be encoded directly, via a hash, hash tree or other encoding.

In some embodiments, and still referring to FIG. 2, one or more steps in forming, modifying, recording transactions in, and authenticating immutable sequential data structure 108 are performed by a network of nodes. Each node may be a computing device as described below in reference to FIG. 7, such as without limitation a validator such as first validator 104; network may be any network interconnecting computing devices as described below in reference to FIG. 10, including without limitation the Internet, a subset of the Internet, a virtual private network, private network, localized network, and/or an intranet. Each node may be designed and configured to participate in, or practice one or more processes described herein for creation, modification, and/or authentication of immutable sequential data structure 108, portions or blocks thereof, and/or transactions.

With continued reference to FIG. 2, in an embodiment, immutable sequential data structure 108 is copied in its entirety to each node. Alternatively or additionally, immutable sequential data structure 108 may be copied to some nodes but not to others; for instance, where the immutable sequential data structure 108 is a block chain or a consensus ledger created for exchanges of virtual currency or other commercial exchanges, the immutable sequential data structure 108 may be copied to all nodes participating in such exchanges. In other embodiments still, various components of the ledger are distributed to various computing devices, such as the nodes in a network. In other embodiments still, subcomponents of the complete ledger are distributed to various computing devices in a network, such that a group of computing devices such as the nodes may each have a copy of the same subcomponent, and in totality, all subcomponents making up the complete ledger are contained in the network. Where immutable sequential data structure 108 is centralized, computing devices that do not possess a copy of the immutable sequential data structure 108 may obtain information from and convey information to the immutable sequential data structure 108 by communicating with the computing device or set of computing devices on which the centralized immutable sequential data structure 108 is maintained. Where immutable sequential data structure 108 is decentralized and multiple copies of the entire immutable sequential data structure 108 are distributed to multiple computing devices, computing devices that do not possess a copy of the immutable sequential data structure 108 may obtain information from and convey information to a copy of the immutable sequential data structure 108 residing on a computing device that does have a copy; requests for information and changes to the immutable sequential data structure 108 may be propagated to all other computing devices having copies of the immutable sequential data structure 108.

Referring again to FIG. 1, immutable sequential data structure 108 may include at least a digitally signed textual element 112 including a physical asset transfer field 116. A physical asset transfer field 116 may include a location or entry where a physical asset transfer datum 120 may be recorded. A physical asset transfer datum 120 may include any datum describing information concerning a physical asset transfer. As used in this disclosure, a physical asset transfer is a process whereby a tangible item is moved from a first location to a second location; a physical asset transfer may include a transfer of property rights in the tangible item, which may be a temporary transfer in which, for instance, an owner of a the tangible item places the item into care and/or custody of a party that will carry the tangible item to the second location, or to an intermediate point, or may be a transfer whereby a receiving party may gain rights of ownership and/or use in the physically tangible item upon receipt. A physical asset transfer may be accomplished in multiple stages, which may correspond to movement of a tangible item by a series of entities, using a series of similar or different modes of movement such as movement via aircraft, ship, truck, train, or the like. Attributes of physical asset transfer may include any variation or element of information subject to use as a physical asset transfer datum 120. A physical asset transfer datum 120 may include information about physical asset transfer such as nature of the transfer, number of units to be transferred, labeling, country of origin, transfer times, transfer destination, number of checkpoints, customer, supplier, material information, transfer regulations, pricing, equipment necessary to transfer and receive materials being transferred, bill of lading, fees, transfer speed, carrier details, interchange details, invoicing details, physical asset transfer details, external parties; details, attestations between participating identities (carrier or carrier controlled) and the like.

Still referring to FIG. 1, physical asset transfer field 116 may be identified within a digitally signed textual element 112 using any suitable element of data, including a flag or label indicating that the digitally signed textual element 112 contains the physical asset transfer field 116; a digitally signed textual element 112 may contain only a single physical asset transfer field 116, such that a label indicating existence of a physical asset transfer field 116 may unambiguously indicate to a validator such as first validator 104 how to locate the physical asset transfer field 116. Alternatively or additionally, a physical asset transfer field 116 may be demarcated by elements indicating beginning and end points of the physical asset transfer field 116 and/or a portion thereof, which may include, without limitation extensible markup language (XML) tags and/or any other element having an agreed-upon significance according to a protocol used in system 100.

With continued reference to FIG. 1, immutable sequential data structure 108 may include at least a digitally signed textual element 112 including a validity flag 124. Validity flag 124 as used herein includes any datum that is interpreted by system 100 as indicating whether first validator 104, or a user of first validator 104, agrees or disagrees with at least a first physical asset transfer datum 120. Validity flag 124 may include an attestation. An attestation as used herein is any confirmation that a validator such as first validator 104, or a user of a validator, agrees to the accuracy of first physical asset transfer datum 120. For example, first physical asset transfer datum 120 may include information pertaining to a final destination of physical asset transfer. An attestation may be generated after a validator or user of the validator reviews a final destination of physical asset transfer contained within first physical asset transfer datum 120 and attests to the accuracy and validity of such information. physical asset transfer datum 120. In an embodiment, generating an attestation functions in system 100 as a final confirmation that validator such as first validator 104 or a user thereof generates with regard to a physical asset transfer datum 120. In an embodiment, entry of attestation may be equivalent to signing a contract confirming accuracy of a physical asset transfer datum 120. In an embodiment, attestation may be performed by user of a validator who may review a physical asset transfer datum 120 and click on “attest to details” in a graphical user interface or the like. By clicking on “attest to details” user may be agreeing to the validity and accuracy of a first physical asset transfer datum 120. In an embodiment, after a user of a validator has clicked on “attest to details” a pop-up window on the validator, or a display in communication with the validator, may appear where the user can review the at least a first physical asset transfer datum 120 that they are attesting to and confirm or cancel the attestation. Once an attestation is complete, a second digitally signed textual element 112 may be generated and proceed to be posted to an instance of the immutable sequential data structure as described in more detail below.

Still referring to FIG. 1, validity flag 124 may be an error flag. Error flag as used herein may include an indication that a validator or user of the validator does not agree to the accuracy of at least a physical asset transfer datum 120 such as first physical asset transfer datum 120. For example, an error flag may be generated when first physical asset transfer datum 120 was entered according to a first assumption early on in the physical asset transfer before all information is known or confirmed; for instance, first physical asset transfer datum 120 may include a price for a physical asset transfer over a particular leg of a physical asset transfer, with the assumption that the physical asset does not require special handling or packaging; whereas a user operating a validator may determine that the physical asset is fragile, requiring protective packaging, that the good is heavy, requiring a dolly or life gate, or the like. In an embodiment, a changed assumption may occasion an increase or decrease in asset transfer pricing, a modification to speed necessary to perform the physical asset transfer, or other changes to physical asset transfer. Thus, error flag may indicate that an agreement has not yet been reached regarding the terms described in a physical asset transfer datum 120 and that a reconciliation process between parties to the physical asset transfer transaction may be necessary. Reconciliation process may, as a non-limiting example, include communication between a first party and a second party, which may take place over any suitable communication channel as described in more detail above in FIG. 1. Communication channel may include for example and without limitation telephonic, electronic, or in-person communication. Reconciliation process may include a process in which an error flag may be accepted and/or rejected by at least a second validator. At least a second validator may accept an error flag from first validator when second validator does not agree to the accuracy of at least a physical asset transfer datum 120 and/or at least a physical asset transfer datum 120 may still be modifiable. For example, second validator may accept an error flag from a validator when at least a physical asset transfer datum 120 contains bad data fields. Bad data fields may include inaccurate data fields and/or data fields that are incomplete, blank, and/or do not contain the most up to date data. In an embodiment, upon accepting an error flag from a validator, second validator may cause status of physical asset transfer to be changed to “failed.” A “failed” status of physical asset transfer may cause a validator and second validator to be unable to continue with physical asset transfer until bad data fields are fixed. A “failed” status may cause the physical asset transfer to fail, so that the physical asset is physically stopped from being transferred and quarantined until the “failed status” is resolved. In such an instance, a validator may fetch new data to fix the bad data fields contained within the at least a physical asset transfer datum 120. Fetching new data may include a new set of data related to the physical asset transfer to be brought in and cause the at least a physical asset transfer datum 120 to be updated. Once bad data fields have been fixed, physical asset transfer status may be changed to “attestation required.” “Attestation required” status may enable physical asset transfer to proceed to be verified by a subsequent validator. At least a second validator may accept an error flag from first validator when at least a physical asset transfer datum 120 may still be modifiable. At least a physical asset transfer datum 120 may be modifiable when information contained within at least a physical asset transfer datum 120 is still mutable at this particular point in the physical asset transfer process. For example, mutable information may include a physical asset transfer whereby information pertaining to a first leg is confirmed, but information pertaining to a second leg is still in flux. Second leg may require selection of a new carrier because the first selected carrier may be unable to participate in the physical asset transfer. Mutable information may also include selection of weight of the physical asset, temperature conditions to be maintained throughout the physical asset transfer, and/or protective packing and/or caging necessary for a particular leg of the physical asset transfer. At least a physical asset transfer datum 120 may not be modifiable when information contained within at least a physical asset transfer datum 120 is immutable at this particular point in the physical asset transfer process as described in more detail below.

With continued reference to FIG. 4, reconciliation process may include a process in which an error flag may be rejected by at least a second validator. At least a second validator may reject an error flag when at least a second validator agrees to the accuracy of at least a physical asset transfer datum 120 and/or when at least a physical asset transfer datum 120 may not be modifiable. This may include for example information contained within at least a physical asset transfer datum 120 that is immutable. For example, a second validator may reject an error flag from a first validator 104 when first validator generated an error flag by accident and information contained within at least a physical asset transfer datum 120 is accurate. For example, first validator 104 may generate an error flag when first validator 104 determines, or a user of first validator 104 believes, that at least a physical asset transfer datum 120 contains bad data fields. Second validator may review data contained within bad data fields and find that at least a physical asset transfer datum 120 does not contain bad data fields and information contained is accurate. Second validator may then transmit a communication to first validator 104 indicating that second validator does not agree with the determination of first validator; this may trigger a reconciliation process whereby first validator and second validator determine validity of the error flag and/or physical asset transfer datum 120.

With continued reference to FIG. 1, reconciliation process may include a third party, such as a remote device and/or user of remote device who may act as an arbitrator of disagreements between parties such as disputes between validity flags 124 raised between first validator 104 and second validator. Remote device may arbitrate disagreements such as disputes pertaining to whether an insurer will cover costs or risks produced by a modification to at least a modified physical asset transfer datum 120 or failure to post such a modification, and/or to correct errors in physical asset transfer data. In such an instance, modified physical asset transfer datum 120 may produce a modified version of physical asset transfer datum 120 containing the modified data. In an embodiment, an additional digitally signed textual element 112 including a second reference to the at least a first physical asset transfer field 116 and at least a second validity flag 124 may be received by the first validator 104 from a second validator. An additional digitally signed textual element 112 may include the at least a first physical asset transfer field 116 that has been examined by second validator. Third digitally signed textual element 112 including a second reference to the at least a first physical asset transfer field 116 may include any reference as described above. In an embodiment, second reference to the at least a first physical asset transfer field 116 may be the same as first reference to the at least a first physical asset transfer field 116. In yet another non-limiting example, second reference to the at least a first physical asset transfer field 116 may be different than first reference to the at least a first physical asset transfer field 116. In an embodiment, both first reference and second reference may uniquely identify the at least a first physical asset transfer field 116. Additional digitally signed textual element 112 includes at least a second validity flag 124. The at least a second validity flag 124 may include an attestation and/or an error flag. In an embodiment, second validity flag 124 that differs from first validity flag 124 may cause remote device to arbitrate dispute between the differing validity flags 124 as described in more detail above. In an embodiment, arbitrating dispute may include a consensus vote of the three verifiers and/or participants to determine how to proceed. In yet another embodiment, dispute may be arbitrated whereby remote device may act as tiebreaker and non-consensus vote is necessary. First validator 104 may post one or more additional digitally signed transactions with additional validity flags 124, which may in turn occasion one or more of the above-described steps to be repeated. Posting one or more additional digitally signed transactions with additional validity flags 124 may be performed by any of the methods as described below at step.

In an embodiment, and still referring to FIG. 1, a physical asset transfer may be associated with a list of validators able to post validity flags 124 as described above; list of validators may be included in one or more digitally signed textual entries as described above. As a non-limiting example, a validator and/or other computing device may create a first entry or set of entries concerning a particular physical asset transfer, where the first entry or set of entries contains one or more validators that are able to post validity flags 124, where “posting” a validity flag 124, as used herein, is a process of creating a digitally signed textual element 112; each of one or more validators may post an attestation indicating that they are members of the list and/or an error flag indicating that they are not members of the list. In the latter case, a reconciliation process may be performed to determine whether a validator that posted an error flag is on the list. Subsequently, a new validator may be added to the list; this may be performed, e.g., by a posting of a digitally signed textual element 112 by a computing device that created first entry or set of entries as described above, or by posting of a digitally signed textual entry identifying the new validator followed by posting of validity flags 124 by validators already on the list, where attestation by all validators on the list may indicate that new validator is now on the list, and an error flag by at least one validator may trigger reconciliation concerning the inclusion of the new validator.

Continuing to refer to FIG. 1, a physical asset transfer datum 120 may be modified, in an embodiment, by posting a second digitally signed textual element 112 containing a reference to a physical asset transfer data field containing the physical asset transfer datum 120 and a replacement physical asset transfer datum 120; this may, for instance, be performed by any validator upon completion of a reconciliation process and/or during any point of validation and/or reconciliation process. In an embodiment, if a physical asset transfer datum 120 as posted is referred to by attestations created by each validator currently on list of validators as described above, physical asset transfer datum 120 may become immutable; that is, further digitally signed textual elements 112 purporting to modify the physical asset transfer datum 120 will be rejected by validators in system 100.

With continued reference to FIG. 1, any digitally signed textual element 112 and/or physical asset transfer datum 120 may be posted in any suitable form, including in machine-readable forms; for instance, each datum and/or digitally signed transaction may be posted in an encoded form that may be stored and/or read efficiently by computing devices configured to perform steps of method 400 as described herein. In an embodiment, a graphical user interface (GUI) may be utilized to display one or more aspects of such data to a user. In an embodiment, GUI may function to translate machine-readable data into one or more fields, buttons, or the like into which users may enter commands indicating, as a non-limiting example, data contained within at least a physical asset transfer datum 120 and/or validity flags 124 including an attestation and/or an error flag. For example, GUI may show unattested physical asset transfer datums 120 with buttons that a user may activate to generate validity flags 124 and generate an attestation or error flag as described above. In yet another non-limiting example, GUI may show a transaction log which may reflect current status of transactions showing physical asset transfer status such as “attestation required” and/or “failed.” In yet another example, GUI may show a status log that may provide status information which may include “pending,” “inaccurate,” and “accurate.” Pending may reflect that no action has yet been taken by a validator in regard to attestation. Inaccurate may reflect that a party and/or validator has raised a flag against one or more of the fields. Accurate may reflect that a party and/or validator agrees to all data contained within the fields.

Still referring to FIG. 1, first validator 104 may be communicatively connected to at least a second validator 128 a-n. At least a second validator 128 a-n may include any computing device as described or alluded to below in reference to FIG. 10.

Second digitally signed textual element 112 further includes and at least a first validity flag 124. At least a first validity flag 124 may include any attestation or error flag as described above.

With continued reference to FIG. 4, one or more devices and/or users may post additional digitally signed transactions to attest to method 400. For example, an additional digitally signed transaction may be entered by second validator 128 a-n, that has previously participated in a transaction, identifying first validator 104, for instance by posting to an address associated with first validator 104 and/or a private key possessed by first validator 104, as described in more detail above. Such a transaction may, for instance, identify a first validator 104 and/or second validator 128 a-n as a valid and authentic party to a physical asset transfer transaction to be recorded or formalized according to method 400, and/or verifying that the device and/or user in question is who they say they are. First validator 104 may enter such a digitally signed transaction similarly identifying and/or validating a second validator 128 a-n. Remote device 132 may enter such a digitally signed transaction similarly identifying and/or validating first validator 104, and/or second validator 128 a-n. Subsequent validators and/or devices may authenticate previous validators and/or devices by evaluating digital signatures linked to previous validators and/or devices. For example, second validator 128 a-n may evaluate at least a first digitally signed textual element 112 signed by first validator 104. Second validator 128 a-n may evaluate first digitally signed textual element 112 signed by first validator 104 by evaluating digital signature linked to first device 104 contained within first digitally signed textual element 112. A first digitally signed textual element 112 containing a digital signature not recognizable by second validator 128 a-n as being linked to first validator 104, may indicate a lack of authenticity of first digitally signed textual element 112 and may cause second validator 128 a-n to raise a validity flag 124 containing an error flag as described in more detail below. In such an instance, this may alert subsequent devices and/or validators as to such as discrepancy. A first digitally signed textual element 112 containing a digital signature recognizable by second validator 128 a-n as being linked to first validator 104, may include authenticity of first digitally signed textual element 112 and may cause second validator 128 a-n to post an additional digitally signed textual element 112 attesting to authenticity of first validator 104. In yet another non-limiting example, second validator 128 a-n may post an additional digitally signed textual element 112 attesting to authenticity of first validator 104 by generating a validity flag 124 such as an attestation as described in more detail below.

At step 410, and still referring to FIG. 4, first validator authenticates first instance of immutable sequential data structure 108. Authentication may include any process or procedure for authentication of an immutable sequential data structure 108 as described above in reference to FIG. 1. For instance, and without limitation, authentication may include evaluation of a hash or series of hashes to determine whether first instance contains a valid hash chain from a current or latest block in immutable sequential data structure 108 to a “genesis block”; in other words, for each block in first instance, first validator 104 may cryptographically hash a block and then compare an output of that process to a hash provided in first instance as a hash of the block. Where one or more other devices such as at least a second validator 126 a-n and/or a remote device 132 have submitted signatures or other data indicating that first instance is authentic, first validator 104 may evaluate the signatures, for instance by decrypting the signatures using associated public keys. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various steps and variations that may be used in authenticating an instance of an immutable sequential data structure.

At step 415, first validator generates at least a second validity flag indicating a determination by the first validator of the validity of the at least a first physical asset transfer field. Generation of at least a second validity flag may include generation of any validity flag as described above in reference to FIG. 1, and/or generation of any datum indicating whether validity flag is an attestation flag or an error flag; for instance, and for illustrative purposes only, a Boolean datum may be generated with a “1” or “true” value indicative of an attestation flag and a and a “0” or “false” value indicative of an error flag. In other words, generation of at least a second validity flag may include determination by first validator 104 whether first physical asset transfer datum is valid or invalid. Determination may be performed, without limitation, by comparison of a value stored in memory of first validator 104 to physical asset transfer datum and/or by comparison of a value entered by a user of first validator 104 to physical asset transfer datum. Determination may include comparison of first physical asset transfer datum to a physical asset transfer datum entered elsewhere in first instance of immutable sequential data structure 108, such as without limitation any element of for example, physical asset transfer profile store 304, physical asset transfer profile 308, carrier details 312, interchanging details 316, invoicing details 320, physical asset transfer details 324, external party details 328, contract info 332, attestation 336, ownable 340, sealable 344, agnostic accessorial 348, delivery accessorial 1 352, delivery accessorial 2 356, pickup accessorial 360, shared accessorial 364, auditable 368, and/or sealable 372. Comparison may include a direct comparison such as a numerical and/or string comparison; comparison may include a comparison of one standard datum, for instance such as a field where data may be entered via a drop-down entries as described above to another. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various ways in which data may be compared as consistent with this disclosure.

At step 420, and with continued reference to FIG. 4, first validator 104 detects a conflict between at least a first validity flag and the at least a second validity flag. Detection of a conflict may include a detection that a validity flag of at least a first validity flag differs from a validity flag of at least a second validity flag. For instance, and without limitation, a second validator of at least a second validator 128 a-n may post one or more validity flags indicating determinations by the second validator of accuracy or truth of one or more data in at least a first digitally signed textual element; first validator may compare data flags generated by first validator, as described above, to each of the one or more data flags, for instance comparing pairs of flags where each pair includes a flag generated by second validator pertaining to a give datum and a flag generated by first validator 104 pertaining to the same datum; if any one pair of compared flags differ, a conflict may be detected. Comparison may similarly be performed regarding validity flags generated by each of a plurality of second validators, where a conflict detected regarding any second validator as described above may qualify as detection of a conflict between at least a first validity flag and at least a second validity flag. Validity flags may be compared to each other according to any suitable form of comparison as described above.

At step 425, and still referring to FIG. 4, first validator 104 transmits an indication of detected conflict to at least a second validator 128 a-n. Transmission may include transmission via any protocol for network communication, for instance as described below in reference to FIG. 10. First validator 104 may transmit to a second validator of the at least a second validator 128 a-n that generated at least a validity flag conflicting with a at least a validity flag generated by first validator 104; first validator 104 may transmit the validity flag to each second validator that generated at least a validity flag conflicting with at least a second validity flag. Alternatively or additionally, first validator 104 may transmit indication to all second validators 128 a-n.

Continuing to refer to FIG. 4, transmission may alternatively or additionally include generating at least a third digitally signed textual element at first validator 104. At least a third digitally signed textual element may be generated using any digitally signed signature as described above. In an embodiment, at least a third digitally signed textual element 112 may include a digital signature that may uniquely identify first validator 104. In an embodiment, at least a third digitally signed textual element 112 may include a digital signature that is the same as digital signature contained within first digitally signed textual element 112. In an embodiment, first digitally signed textual element 112 may contain a digital signature that is different from a digital signature included in at least a third digitally signed textual element 112. At least a third digitally signed textual element 112 includes a first reference to the at least a first physical asset transfer data field. First physical asset transfer data field may be associated with an identifier, which may be locally or globally unique, and/or with an identifier of a physical asset transfer contract or agreement or the like that memorializes a physical asset transfer to be memorialized according to method 400. In an embodiment, a standard number or other identifier may identify a given field within a contract or agreement, while a unique identifier may be used to distinguish contract or agreement from other contracts being posted to first instance of the immutable sequential data structure. First physical asset transfer data field may be associated with an identifier of a user who is performing physical asset transfer. For example, first reference may be to an identifier of user who is performing physical asset transfer which may include a unique identifier of user such as user's name or date of birth. In an embodiment, identifier of user may include a unique identifier that may be used to distinguish one user from another user and to link a user with a specific contract or agreement. For example, identifier may consist of a unique set of characters, numbers, letters, and/or any combination of the above which may link a contract or agreement with a specific user as well as distinguish contract or agreement from other contracts or agreements being posted to first instance of the immutable sequential data structure.

Still referring to FIG. 4, at least a third digitally signed textual element may include at least a second validity flag as described above; inclusion of at least a second validity flag in at least a third digitally signed textual element may be performed according to any process for inclusion of at least a first validity flag in at least a second digitally signed textual element. First validator 104 may posting the at least a third digitally signed textual element to the first instance of the immutable sequential data structure; posting to the first instance of the immutable sequential data structure may be performed in any manner suitable for posting a digitally signed transaction to an immutable sequential data structure as described above; posting may include adding to an active block of immutable sequential data structure, either a local copy of the immutable sequential data structure or a remote copy of the immutable sequential data structure by transmitting the at least a second digitally signed textual element 112 to another device and/or validator having a copy of an active block and/or of immutable sequential data structure; immutable sequential data structure with the at least a second digitally signed textual element 112 posted to it may be distributed to one or more other devices and/or validators including one or more devices and/or validators acting as participants in physical asset transfer contract or agreement, agreed to, and/or memorialized according to method 400. With continued reference to FIG. 4, after transmission, a reconciliation process may proceed as described above.

In an embodiment, and continuing to refer to FIG. 4, first validator 104 may receive a second instance of immutable sequential data structure 108; second instance may have additional entries in a current block, one or more additional blocks, or the like. Second instance of the immutable sequential data structure may include comprises at least a third digitally signed textual element containing at least a second physical asset transfer field populated with at least a second physical asset transfer datum of the physical asset transfer; second physical asset transfer field may include, without limitation, a physical asset transfer field that is associated with the same physical asset transfer to which first physical asset transfer is associated. For instance, and without limitation, at least a second physical asset transfer datum may include a modification of the first physical asset transfer datum. Modification may be performed, as a non-limiting example, as a result of a reconciliation process as described above; alternatively or additionally, modification may include or constitute an attempt by a user operating one of at least a second validator 128 a-n to modify a previously posted physical asset transfer datum, for instance to correct an error and/or in response to a change of circumstances. As noted above, modification to a physical asset transfer datum may be prohibited by system 100 where all devices of a list of signing devices have performed attestations of the physical asset transfer datum. In an embodiment, first validator 104 may identify a list of signing devices; this may be performed by reference to a digitally signed textual element in first and/or second instance of immutable sequential data structure listing signing devices as described above, by retrieval of such a listing from a datastore and/or database on or accessible to first validator 104, by identifying an originating and/or first posting device and receiving the listing from that device, or the like. First validator 104 may determining that each device of the list of signing devices has posted an attestation of the at least a first physical asset transfer datum as described above in reference to FIG. 1 and reject the at least a second physical asset transfer datum. Rejection may include, without limitation, posting an error flag as described above to indicate an improper modification, refusing authentication of second instance and/or a block of second instance containing at least a second physical asset transfer datum, and/or ignoring at least a second physical asset transfer datum in future iterations of methods disclosed herein, such as method 400. Alternatively, first validator 104 may determine that at least a device of the list of signing devices has not posted an attestation of the at least a first physical asset transfer datum; first validator 104 may then proceed with validation of at least a second physical asset transfer datum, for instance as described above. As a non-limiting example, first validator 104 may generate least a fourth digitally signed textual element including at least a first reference to the at least a first physical asset transfer, at least a first reference to the at least a second physical asset transfer, and at least a third validity flag. First validator 104 may post the at least a fourth digitally signed textual element to the immutable sequential data structure.

Still referring to FIG. 4, at least a second physical asset transfer datum may not include a modification of the first physical asset datum; for instance, at least a second physical asset transfer datum may include a datum referring to a later stage in physical asset transfer as described in reference to FIG. 5, below. First validator 104 may engage in any processes as described herein regarding at least a second physical asset transfer datum. For instance, and without limitation, first validator 104 may generate least a fourth digitally signed textual element including at least a first reference to the at least a first physical asset transfer, at least a first reference to the at least a second physical asset transfer, and at least a third validity flag; first validator 104 may post the at least a fourth digitally signed textual element to the immutable sequential data structure.

With continued reference to FIG. 4, steps of method 400 may be repeated one or more times for different checkpoints, which may correspond to stages in a physical asset transfer process. Referring now to FIG. 5, a method 500 for receiving a second textual element of an immutable sequential data structure at a first validator is illustrated. At step 505, first validator 104 receives a second textual element of an immutable sequential data structure, wherein the second textual element of the immutable sequential data structure includes at least a second digitally signed textual element 112 containing at least a second physical asset transfer field 116 populated with at least a second physical asset transfer datum 120.

In an embodiment, contract or agreement governing physical asset transfer may be divided into different checkpoints that may enable all parties to agree to processes physical asset transfer at particular stages of the physical asset transfer, when it is possible for all parties to be aware of likely physical asset transfer parameters. For example, a party that is going to perform the physical asset transfer on the second leg of the physical asset transfer may wish to verify the conditions of the physical asset transfer and/or determine what packaging or equipment must be involved in the physical asset transfer, prior to attesting to terms describing such conditions, packaging, or equipment. By attesting and dividing portions of the contract or agreement governing the physical asset transfer, method 400 may enable parties to agree to some portions of a shipment process while permitting them flexibility to negotiate and reassess subsequent portions. In an embodiment, attestations may be performed at various stages of the physical asset transfer. Attestations may be categorized and named to reflect task that is being attested to. For example, attestations may include physical asset transfer profile store, physical asset transfer profile, carrier details, attestation, interchange details, physical asset transfer details, agnostic accessories 1, delivery accessories 2, pick up accessories, and/or shared accessories. In an embodiment, physical asset transfer profile may contain information related to a specific physical asset transfer. Physical asset transfer profile may include for example, carrier details, interchange details, invoicing details, physical asset transfer details, external parties' details, and moments of attestations between participating identities (carrier or carrier controlled).

Referring now to FIG. 8A-F screenshots illustrating exemplary embodiments of a graphical user interface (GUI) that a user may interact with and/or use to perform steps and processes in any of the methods described in this disclosure. GUI may function to translate machine-readable data into one or more fields, buttons, or the like into which users may enter commands indicating, as a non-limiting example, physical asset transfer data and/or validity flags. For instance, and for illustrative purposes only, FIG. 5A shows an initial step of data review and attestation for a physical asset transfer at controlling carrier attestation stage. In an embodiment controlling carrier may attest carrier details 312 and attestation of contract information 332 as described above in FIG. 3. FIG. 5B shows a pop-up screen that allows a user to select fields with bad data and generate an error flag by selecting “flag details.” FIG. 5C shows a screen where a user can review data they are attesting to and confirm or cancel the attestation. Confirming the attestation may allow the user to proceed on to the next checkpoint, while canceling the attestation may result in fetching new data and/or a reconciliation as described in more detail above in FIGS. 1-7. FIG. 5D shows a step of data review and attestation at interchange. In an embodiment, interchange may allow for data pertaining to interchange gateway code, interchange zip code, and/or driver company to be modified and/or generate validity flag as to this information. FIG. 8E shows confirmation of interchange attestation details. FIG. 8F shows an exemplary embodiment of a billing review attestation moment and seal physical asset transfer option.

Referring now to FIG. 9, a method of distributed, cryptographically secured data validation is illustrated. At step 905 a first validator 104 receives a first instance of an immutable sequential data structure, wherein the first instance of the immutable sequential data structure includes at least a first digitally signed textual element containing at least a first physical asset transfer field populated with at least a first physical asset transfer datum of a physical asset transfer; this may be implemented as described above in reference to FIGS. 1-8F. For instance, and without limitation, receiving first instance of the immutable sequential data structure may include receiving at least a block of the immutable sequential data structure. As a further non-limiting example, receiving first instance of the immutable sequential data structure may include receiving a link to the immutable sequential data structure. At step 910 first validator 104 authenticates first instance of immutable sequential data structure; this may be implemented as described above in reference to FIGS. 1-8F. At step 915 first validator 104 generates at least a second digitally signed textual element, the at least a second digitally signed textual element containing a reference to the at least a first digitally signed textual element and at least a first validity flag indicating a determination by the at least a second validator of the validity of the at least a first physical asset transfer field; this may be implemented as described above in reference to FIGS. 1-8F. At least a first validity flag may include an attestation. At least a first validity flag may include an attestation error flag.

Still referring to FIG. 9, at step 920 first validator 104 transmits a second instance of the immutable sequential data structure to a plurality of second validators, wherein the second instance of the immutable sequential data structure contains the at least a second digitally signed textual element; this may be implemented as described above in reference to FIGS. 1-8F. At step 925 first validator 104 receives, from at least a second validator of the plurality of second validators, an indication of a conflict with the first validity flag; this may be implemented as described above in reference to FIGS. 1-8F. For instance, and without limitation, receiving the indication of the conflict may include receiving a fourth digitally signed textual element including a digital signature linked to the at least a second validator; this may include determining that the digital signature is not linked to a validator identified in a previous digitally signed transaction as an authentic party.

At step 930, and continuing to refer to FIG. 9, first validator 104 generates, as a function of the indication of the conflict, a third digitally signed textual element referencing the first digitally signed textual element; this may be implemented as described above in reference to FIGS. 1-8F. Where first validator 104 determines that the digital signature is not linked to a validator identified in a previous digitally signed transaction as an authentic party, generating the third digitally signed textual element may include generating an error flag indicating that the fourth digitally signed textual element is inauthentic. As a further example, first validator 104 may determine that at least a first validity flag included an error and generate third digitally signed textual element modifying the at least a first validity flag. Generating the third digitally signed textual element may include determining that the at least a first physical asset transfer datum included an error and generating the third digitally signed textual element modifying the at least a first physical asset transfer datum. First validator 104 may transmit a third instance of the immutable sequential data structure to a plurality of second validators, wherein the third instance of the immutable sequential data structure contains the third digitally signed textual element; this may be implemented as described above in reference to FIGS. 1-8F.
